Answer to Question 1

ANS: C
For an intramuscular injection into an adult deltoid muscle, a 25-gauge, 1-inch needle is recommended. An 18-gauge needle is too big. While a 23-gauge needle can be used, a 1/2-inch needle is too small. A 27-gauge, 5/8 -inch needle is used for intradermal.

Answer to Question 2

ANS: A
The reduced glomerular filtration rate delays excretion, increasing chance for toxicity. In older adults, gastric motility and liver mass decrease. Esophageal stricture is not a physiological change associated with normal aging.
